It is thought her condition is caused by a Tarlov cyst that developed on her spine following a tumble she took down some stairs in 2001.

The orgasms began to trouble Ramsey in 2008, when she entered into a sexual relationship with a new partner. "I had constant orgasms for four days," she said. "I thought I was going mad."

In the aftermath of that episode, Ramsey says the slightest movement can triger an orgasm.

"Imagine feeling aroused for no reason other than you got up that day," she said. "I've even had one in public. I was travelling home on the train and it was a bit of a bumpy ride.
